Elliott Cutters
1 / 5
Dome PDC inserts consist of a multilayer structure of diamond and transition layer, improving impact resistance greatly. This makes dome PDC inserts the best alternative for roller cone applications.
Priority for rear row teeth, auxiliary for main teeth. As rear row teeth, it buffers impact and protects main cutting parts from gravel damage.
Flat and smooth tooth surface with large contact area, delivering high cutting efficiency and outstanding wear resistance. Uniform force bearing avoids local wear with high cost performance.
Priority for main teeth. It crushes formation rocks quickly; as rear row teeth, it assists cutting and provides gauge protection to extend bit life.
Sharp tapered tooth tip with extremely strong penetration, reducing drilling resistance in medium-hard to hard formations. Disperses stress effectively with excellent impact toughness.
Exclusively for main teeth. Its core advantage is sharp penetration for hard formation crushing; not recommended for rear row teeth due to small contact area.
